HOLDING AND SPACING DEVICE FOR PHOIOGRAPHIC FILMS.

SPECIFICATION forming part of Letters Patent No. 632,736, datedSeptember 12, 1899. Application filed January 28,1899. Serial No.703,663. (No model.)

To @ZZ whom t may concern.'

Be it known that I, HORACE W. MUNsEY, a citizen of the United States,residing at Ohester, in the county of Delaware, State of Pennsylvania,have invented a new and useful Improvement in Holding and SpacingDevices for Photographic-Film Rolls, which improvement is fully setforth in the following speciication and accompanying drawings.

My invention consists of a device for holding a photographic-film rolland spacing the lilm accurately preparatively to cutting or severing thesame.

Figure l represents a perspective View of a holding and spacing devicefor a photographic-nlm roll embodying my invention. Fig. 2 represents abottom plan View thereof. Fig. 3 represents a longitudinal section online ac, Fig. 2. Figs. 4 and 5 represent perspective views of otherforms of my invention.

Similar letters of reference indicate corresponding parts in theiigures.

Referring to the drawings, A designates a stock or head having Withinthe same the channel B, which is open at both ends for the passagetherethrough of the photographic Iilm C and the protector D therefor, ifthe latter is employed.

E designates a frame formed of heavy wire or other suitable materialhaving its ends inturned, as at F, producing journals, which enter thespool G, on Which the iilm is rolled, whereby said spool may turn onsaid journals in the unwinding of the lm therefrom. Bearing against thecross-piece H of the frame E are the springs J, which are located withinthe stock A and serve to hold the spool close to the latter, a portionof the sides of the stock being recessed, as at K, to permit the lm-rollto enter the same, so that the heads or flanges of the spool overlap theadjacent portions of the sides of the stock, and thus steady the spooland prevent improper lateral movement or shifting thereof. The walls ofthe recesses K act as seats or contacts for the surface of the roll,which is pressed against said Walls, so that improper unwinding of thelatter is prevented.

In the upper wall of the stock is the opening I., through which thenumber of an advanced film to be severed or cutl is presented,indicating that said iilm isproperly spaced outside of the stock.

The operation is as follows: The film to be cut or severed is passedthrough the channel with the protector there-for and unrolled to theproper extent, when a number appears centrally at the opening L, saidlil in then being outside of thestock. The protector D is 6o then turnedup on the top of the stock and the projecting film is cut along the edgeM of the stock, said edge preferably projecting and acting as a gage, sothat the cut is made true and uniform throughout its length. Anothersection of the film and corresponding length of the protector are thenunrolled until the next number on the protector appears in the openingL, when said section is properly spaced outside of the stock ready 7o tobe cut or severed, as in the previous case. Vhen the spool is to beremoved, the frame is drawn or pushed back, so that the spool recedesfrom the stock, When the journals F may be Withdrawn from the spool, theside pieces of the frame E being sufficiently elasv tic to yield whenspread apart. A spool With a fresh ilm may now be applied to the frame,the journals readily springing into the opening or bore of said spool,When the frame un- 8o der pressure of the springs J returns to itsnormal position, thus properly locating the spool, when the film andprotector may be passed through the channel B and be operated in themanner as in the previous case. In order to conveniently operate saidframe, the under side of the stock is recessed as at M', so that thecross-bar I-I of said frame is conveniently accessible to be engaged bythe fingers.

In Fig. 4 I show elastic bands N, employed in lieu of the springs J, forobtaining the requisite pressure on the spool and film, and the stock isformed of separate sections I and Q, connected by the tongues andgrooves 95 R S, whereby they may be disconnected in order to locate thefilm and protector in the channel T existing between said sections, saidchannel being shown in dotted lines in said Fig. 4. In Fig. 5 I showanother form of conroo struction, in which the body of the deviceisformed of pieces of metal spread out to produce a chamber therein toreceive the filmroll, said pieces being slotted, whereby the fingers maybe inserted through the same to handle the roll, said pieces beingconnected by a bent piece which causes them to be elastic and close onthe nlm-roll spool, so as to impart proper pressure or tension thereto.In other respects said body or stock is provided With a cutting-gageedge and a spacingopening and has a roller on its lower edge to bearagainst the film to prevent bellying or buckling of the same between theroll and gage edge.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

I. In a holding and spacing device for a film or web, the combination ofa stock having a channel therethrough, a holder for the film or Webadjacent one end of the stock, and elastic means for Vmaintaining` theholder uvieldingl yin contact with the end of the stock.

l 2. In a holding and spacing device for a photographic-film roll, astock having a channel therethrough, a spacing-opening therein, and acutting edge at the discharge end of said channel, a film-roll holder atthe inlet end of said channel, bearings on the stock for said holder,and elastic means 'for pressing said lm-roll firmly against said stock.

3. In a holding and spacing device for a photographicfilm roll, a stock,a Iilm -roll holder thereon, said stock having alongitudinally-extending channel therethrough, a spacing-openingtherein, a recess at one end of said channel and a cutting edge at theother end thereof, bearings on the stock for said holder, and elasticmeans for maintaining the holder yieldingly in said recess in contactwith the stock, the heads of the holder overlapping the side Walls ofsaid recess. 4. Astock, a sliding frame thereon, means on said frame forjournaling a photographiclm roll thereon, and a spring bearing againstsaid frame for retaining it in operative position on said stock, saidstock having a channel therein for guiding the film from the rolll tothe opposite end of the stock,

said end constituting a cutting-gage.
